Serial No. 399,278.

My invention relates to improvements in wire tying devices, and the object of my invention is to construct a hand actuated device which can be manually carried and used for securing the canes of grape vines to the horizontal wires which are generally used for supporting the vines. A further objectof my invention is to construct a device that can be operated by one hand which leaves the 6 other hand of the user free to gather the vine canes into place and hold them whilst they are being tied.

My invention consists of a wire tying device constructed and arranged all as hereinafter more particularly described and illuslrated in the accompanying drawings in which,

Fig. 1 is a side elevational view of my device.

6 Fig. 2 is an inverted plan view of a fragmentary portion of my device showing the tying wire partially wrapped around the vine.

Fig. 3 is a similar viewto Fig. 2 showing the wire tied.

Fig. 4 is adetached perspective view of one of the wire bending levers of my device. Fig. 5 is a detached perspective v1ew of the other wire bending and cutting member 36 of my device, and

6 is a perspective view of a portion of a grape vine cane and supporting wire therefore tied together by a tie wire formed by my device. 1 l Like characters'of reference ind cate corresponding parts in'the diflerent views.

My device comprises a mam frame 1 formed at oneend thereof with a hand grip 2, the frame being formed with a recess at the end remote from the hand grip 2.

The recess forms in itself a jaw 3 and in thetop of such jaw and mounted upon the frame I provide a plate 4 which extends laterally of one side of the frame. The projecting side of the plate 4 is furnished with an "orifice 5 and a V-shaped slot 6 extending inwardly from the edge of the plate. The end 7 of such slot is undercut so that it forms a cutting edge.

Underneath the plate 4 I mount a wire bending and cutting plate 8 which is pivotally mounted upon a pin 9 extending from the plate 4, the plate 8 sliding upon the plate 4. The plate .8 is formed with a cutting edge 10and with a recess 11 formed between such cutting edge and the rounded portion of the plate surrounding thepin 9. The edge 10 is so formed upon the plate 8 that as such plate 8 oscillates below the plate 4 the cutting edge 10 moves across the orifice 5 in the plate 4 and the recess 11 moves along the slot 6 in the plate 4 as shall be hereinafter explained. 1 r J A finger grip lever 13 is pivotally mounted upon the frame 1, being swingable about a 5 pin 14, the lever 13 being held in resilient spaced relation to the hand grip 2 by a spring 15 which extends between its upper end and the hand grip 2. The upper endrof the lever 13 is connected to the rear end of the plate 8 by means ofa link '16, and upon reference to the drawings it will be readily seen that the spring 15 will normally retain the hand grip lever 13 away from the hand grip 2 and the plate 8 fully drawn back in the position illustrated in Fig. 2 in which the cutting edge 10 of such plate isclear of the orifice 5 in the plate 4. V 17 is a tying wire'bending lever adapted vto be actuated by the thumb of the operator a and pivotally mounted at its forward end to theframe 1 upon a pin 18. The lever 17 is formed with a slot 36 through which the pin 18 extends, such pin being slidable within the slot so that the swinging radius of the forward portion of the lever may be altered to accommodate canes of various sizes. Upon the upper forward portion of the leverI form a recessed portion 19 which is positioned underneath the plate 4, and 20 is a spiral spring extending upwardly from the lever 17 to the wire holder support 21.

Rotatably mounted upon the frame 1 above the jaw 3 is a feed roller 22 the periphery of which is'formed with a wire receiving groove, such roller being furnished with a finger and thumb grip 23. 24 is an arm extending upwardly from the frame 1 and carrying a bell crank lever 25 which is pivotally mounted thereon by a pin 26. The inner end of this lever carries a roller 27 which engages the feed roller 22 and is held in contact there with by a spiral spring 28 extending from the other end of the bell crank lever to the top of the arm 24. The point of contact of this roller is vertically above the orifice 5 in the plate 4.

Supported above the frame 1 I position a wire reel 29 which is pivotally mounted upon a pin 30 extending from the top of the arm 21.

In Figures 1, 2, 3 and 6 of the drawin s a portion of the grape vine cane is indicated by the numeral 31 and a portion of the horizontal supporting wire to which it is tied by the numeral 32.

The operation of my device is as follows:

In using my device the hand grip 2 and lever 13 are held in one hand of the operator and the tie wire 33 is fed downwardly through the orifice 5 so that it extends across the jaw 3, and a. sufficient length is fed down by rotating the roller 22 to form a loop and knot about the cane and its supporting wire.

The cane 31 and its supporting wire 32 are then held together in the operators other hand and placed within the aw 3, the tying wire 33 being pushed inwardly in the jaw and having its free end extending through the notch 34 in the forward end of the lever 1?, the grape vine and tying wire lying in the recess 19 in such lever.

The lever 17 is then actuated by the thumb of the operator so that its forward end swings upwardly and moves the free end of the tying wire into the slot 6 in the plate 4. hen the tying wire is in this position the lever 13 is pulled towards the hand grip 2 which swings the link 16 forwardly to oscillate the plate 8 across the inner face of the plate 4.

During the first operation of this oscillation of the plate 8, the cutting edge 10 moves across the orifice 5 in the plate 4 and cuts the wire at the point where it emerges from this orifice, and during the remainder of the oscilla-tion of such plate 8 the cut end of the partially formed loop lies within the recess 11 of the plate 8 and as this recess moves along the slot 6 in the plate 1- the two ends of the wire are twisted upon each other to form a knot 35, as illustrated in Figure 6. The under-cutting at the end 7 of the slot 6 and the bevelling of the recess 11 in the plate 8 pro vides a clearance for the ends of the loop during its twisting operation.

The tying operation is then complete and upon releasing the lever 17 and the finger grip lever 13 they both return to their original positions and are ready for a second operation.

From the foregoing description it will be seen that I have constructed a very simple and efiicient type of tying device, which can be readily operated and which will save a great deal of time in the tying of grape vines which,

heretofore, has been solely done by the hand.
